FREY is one of the biggest players in the game when it comes to high-power electric mountain bikes. Now, the company is making waves with its newest model, the FREY Dopamine 2.0.

The e-bike was just unveiled today and offers an update to the company’s innovative high-performance ride.

The full-suspension electric mountain bike includes both an upper and lower idler pulley in the pedal drivetrain, eliminating pedal kickback and offering a smoother pedaling experience. Combined with the high-pivot suspension using a RockShox Deluxe 205*65mm rear shock and RockShox YARI 29*160mm front fork, the bike should be able to handle some serious trails.

But of course FREY bikes aren’t just designed for cruising downhill. They’re known as some of the highest-power electric mountain bikes in the game, and the Dopamine 2.0 doesn’t disappoint. The Bafang M560 mid-drive motor may carry a 500W designation on the spec sheet, but that relatively modest continuous power rating is betrayed by the stump-pulling 140 Nm torque rating, meaning hill climbs can just about tackle terrain steep enough to run into traction issues before power issues.

With a top speed of 45 km/h (28 mph), it can make quick work of the flats, too.

Carrying that power is a chain-driving SRAM NX11s drivetrain, giving riders plenty of gear ratios to choose from. And the FREY Dopamine carries one more trick up its sleeve, too.

If you’ve followed electric mountain bikes for any amount of time, you’ll know that one feature is as rare as hen’s teeth: a throttle. In addition to offering high value with factory direct supply, one of FREY’s biggest differentiators is that the company offers higher power motors that come complete with throttles installed.

They’re removable for riders who want to maintain a pure pedal-assist experience, but many US riders enjoy the type of riding experience made possible by the high-power setup that comes on at the push of a throttle.

As the company explained:

“The FREY dopamine is a high-performance full-suspension e-MTB with an electric throttle designed specifically for aggressive and comfortable trail riding. It is and enduro electric assist bike capable of easily and quickly ascending and comfotably descending slopes.”

The FREY Dopamine 2.0 sports a 48V 15Ah battery for 720Wh of capacity. Rounding out the hardware on the bike are Magura MT5e quad-piston hydraulic disc brakes, a KS 900i dropper seat post, a display integrated into the frame’s top tube, Michelin and Maxxis tire options in 29 and 27.5 inch sizes.

The bike is available in three frame sizes and is priced at US $4,980 as part of its launch pricing. The first bikes will begin shipping in mid-April using a mixed distribution model, shipping both factory-direct and maintaining local warehouses in the US and several other countries.

World's largest EV maker unveils new sodium battery electric motorbikes

Yadea, which has claimed the title of the world’s largest electric vehicle maker for seven years running, has just announced a new electric motorbike powered by the company’s innovative HuaYu sodium-ion battery technology.

Yadea has long dominated the electric two-wheeler and three-wheeler market globally, but has generally relied on both lithium-ion and lead acid batteries to power its vehicles in different markets.

The newly unveiled electric scooter uses Yadea’s recently introduced sodium battery technology, offering what the company says is outstanding performance in range, charging speed, and safety. Using the HuaYu Sodium Superfast Charging Ecosystem presented by Yadea, the battery can reach 80% charge in just 15 minutes, providing greater convenience for riders.

Yadea’s sodium battery has successfully passed more than 20 safety tests, many focusing on its resistance to fire and explosions under extreme conditions like punctures and compression.

Yadea’s new sodium battery offers an energy density of 145 Wh/kg and a lifespan of up to 1,500 cycles at room temperature, with the company rating it for a five-year useful lifespan. It also includes a three-year warranty for added assurance.

With excellent low-temperature capabilities, the battery retains over 92% of its discharge capacity at -20°C, making it well-suited for colder climates.

Sodium batteries present major advantages

Most electric vehicles used in the West, especially electric two-wheelers, rely on lithium-ion batteries for their high energy density. But sodium-ion batteries offer many benefits over traditional lithium-ion batteries.

Sodium is an abundant element on the planet and is easily accessible, unlike lithium, which is concentrated in specific regions and often expensive to extract. This abundance can make sodium-ion batteries cheaper to produce, reducing costs for EV manufacturers and potentially making electric vehicles more affordable.

Lithium mining also has environmental challenges, such as water depletion and habitat destruction. Sodium, on the other hand, can be sourced from seawater or common salts, offering a more sustainable and environmentally friendly option.

Sodium-ion batteries are less prone to overheating and thermal runaway compared to lithium-ion batteries. This makes them inherently safer for electric vehicles, reducing the risk of fires and improving consumer confidence in EV technology.

Sodium-ion batteries perform better than lithium-ion in cold climates. Lithium-ion batteries struggle with capacity retention in freezing conditions, but sodium batteries maintain efficiency, making them ideal for EVs in colder regions.

Sodium batteries still have challenges to overcome

While sodium-ion batteries are promising, they currently have a lower energy density than lithium-ion batteries, meaning they store less energy per unit of weight.

For EVs, this translates to shorter driving ranges for the same-sized battery. That’s especially important in electric two-wheelers like motorbikes and electric bicycles, which don’t have much extra space for storing bulky batteries.

However, advancements in cathode materials and battery architecture are quickly closing this gap, which Yadea has demonstrated. These sodium-ion batteries still can’t match the energy density of lithium-ion batteries, but as they continue to improve their energy density, the technology’s other major advantages provide encouraging signs for larger adoption in the industry.

Yadea’s status as a major electric motorbike maker also means that its adoption of sodium-ion battery technology could help lead the entire industry towards this battery chemistry, bringing safety and performance benefits along with it.

Last year I had the unique opportunity to visit one of Yadea’s global manufacturing sites.

CES2025 | John Deere autonomous mower promises a perfect cut, every time

CES2025 | John Deere autonomous mower promises a perfect cut, every time

At CES2025, the impressively built-out John Deere exhibit was all about automation. Autonomous job sites, autonomous farms … but it was this new, battery electric, autonomous lawn mowing robot that stole the show.

The self-driving Deere mower robot was positively dwarfed by the giant farm machinery surrounding it, but it continues to prove that humans will pack bond with anything as more than one burly-looking and grizzled man asked what its name was. (It’s Howard. I’ll fight you.)

For his part, Howard packs a 21.4 kWh battery pack that runs a suite of electric motors that includes a drive motor and three cutting blade motors spread across a 60 inch cutting deck – but it’s not the electric motors that make John Deere’s little robot mower cool, it’s the way it works.

See, instead of using “just” GPS data or “just” repeating a pre-recorded run, Howard can do something in between. The way it was explained to me, you would ride the stand-up mower around the perimeter of the area you wanted to mow, select a pattern, then hop off, fold up the platform, and let it loose. Howard mows just the way you would, leaving you to focus on edging, planting, or (let’s face it) schmoozing with the clients.

It’s exactly the sort of help landscapers are looking for.

But that should come as no surprise, of course. John Deere, perhaps more than most companies, knows its customer. “We’ve been in the turf business for 60 years — it’s a core part of Deere,” says Jahmy Hindman, chief technology officer at John Deere, explaining things beautifully. “The work that’s being done in this industry is incredibly labor intensive … they’re not just doing the mowing work. They’re doing the tree trimming, maintaining flowerbeds and all these other jobs. The mowing is table stakes, though, for them to get the business. It’s the thing they have to do in order to get the higher value work.”

Tim Lewis, lead engineer with the commercial automatous mower, told Lawn & Landscape that the industry in general has a high turnover rate as well, making it difficult to hang to people who know where one job ends and another begins. “There’s a lot of nuances it takes to do these jobs effectively,” he explains, “so “Autonomy can help with that.”

The John Deere autonomous commercial mower (there’s no snazzy alphanumeric, yet) leverages the same camera technology as other Deere autonomous machines, but on a smaller scale (since the machine has a smaller footprint). With two cameras each on the front, left, right, and rear sides of the little guy, he has a 360-degree view of the world and enough AI to lay down a pattern, avoid an obstacle, and shut off if it thinks it’s about to mow down something (read: someone) it shouldn’t.

John Deere will have Howard on display through tomorrow at CES in the LVCC’s West Hall. If you’re in town, be sure to go say hi.
